| Matthew Henry's Concise Commentary 30:10 Slander not a servant to his master, accuse him not in small matters, to make mischief. 11-14. In every age there are monsters of ingratitude who ill-treat their parents. Many persuade themselves they are holy persons, whose hearts are full of sin, and who practise secret wickedness. There are others whose lofty pride is manifest. There have also been cruel monsters in every age. 15-17. Cruelty and covetousness are two daughters of the horseleech, that still cry, Give, give, and they are continually uneasy to themselves. Four things never are satisfied, to which these devourers are compared. Those are never rich that are always coveting. And many who have come to a bad end, have owned that their wicked courses began by despising their parents' authority. 18-20. Four things cannot be fully known. The kingdom of nature is full of marvels. The fourth is a mystery of iniquity; the cursed arts by which a vile seducer gains the affections of a female; and the arts which a vile woman uses to conceal her wickedness. 21-23 Four sorts of persons are very troublesome. Men of low origin and base spirit, who, getting authority, become tyrants. Foolish and violent men indulging in excesses. A woman of a contentious spirit and vicious habits. A servant who has obtained undue influence. Let those whom Providence has advanced from low beginnings, carefully watch against that sin which most easily besets them.
Pulpit CommentaryVerse 13. - A generation, oh, how lofty are their eyes! The third sin is pride and arrogance (see on Proverbs 6:17; 21:4). "Lord," said the psalmist, "my heart is not haughty, nor mine eyes lofty" (Psalm 131:1). The prophet rebukes "the stout heart of the King of Assyria and the glory of his high looks" (Isaiah 10:12). Their eyelids are lifted up; in supercilious disdain. "Inde Proverbio dicimus," says Erasmus ('Adag.'), "attolli supercilium, fastidium indicantes" (s.v. "Arrogantia").
Gill's Exposition of the Entire BibleThere is a generation, O how lofty are their eyes! and their eyelids are lifted up. Above others, on whom they look with scorn and contempt; as those do who have more riches than others, and boast of them; they despise their poor neighbours, and disdain to look upon them: and such also who have more knowledge and wisdom than others, or at least think so; they are puffed up in their fleshly minds, and say of the illiterate or less knowing, as the proud Pharisees did, "this people, who knoweth not the law, are cursed": and likewise those who fancy themselves more holy and righteous than others; these, in a scornful manner, say, "stand by thyself, I am holier than thou"; and thank God they are not as other men are, as publicans and sinners; see Proverbs 19:4. Hence Pliny (i) says, that in the eyebrows there is a part of the mind; those especially show haughtiness; that pride has a receptacle elsewhere, but here it has its seat; it is bred in the heart, but here it comes and here it hangs: wherefore Juvenal (k) calls pride and haughtiness, "grande supercilium"; and proud haughty persons are said to be supercilious. (i) Nat. Hist. 1. 11. c. 37. (k) Satyr. 6. v. 168.
